Gornje Podunavlje. 20/11/2007; Vojvodina; 22,480 ha; 45°45'N 018°57' E. Special Nature Reserve; Important Plant Area; IBA. A marsh complex along 36km of the Danube River, forming a natural unity with the Gemenc and Kopacki Rit Ramsar sites in Hungary and Croatia respectively. The site is a unique mosaic of aquatic, wetland, and terrestrial ecosystems and an important centre of ecosystem, species, and genetic diversity. A large number of rare and nationally or internationally threatened plant species and their communities are supported, as well as vulnerable habitats. This area is the habitat of rare plant species such as winter aconite Eranthis hyemalis, water violet Hottonia palustris, and mare's tail Hippuris vulgaris, an important spawning place and a migratory route of fishes, a nesting place of the white-tailed eagle Haliaeetus albicilla and the black stork Ciconia nigra, as well as the habitat of the largest population of the red deer Cervus elaphus in Serbia. Especially rich ethnic and folkloric traditions converge in the area, which is a centre for traditional festivals. Hunting and commercial and sport fishing are well developed, and controled forestry is practiced within the site. The effects of previous drainage and irrigation works present a threat, as do eutrophication and invasive alien species. Ramsar site no. 1737. Most recent RIS information: 2008.
